Since the beginning a century ago, forest management in Thailand has undergone many changes, in form of reclassifications, name changes and management changes. All this has resulted in a division of 16 regions with 5 branches in 2002. Five regions in Central-East with 28 national parks, four regions in the South with 39 national parks, four regions in the Northeast with 23 national parks and eight regions in the North with 65 national parks.

Royal Forest Department was reclassified from the Ministry of Interior to the Ministry of Kasettrathikarn in 1921. A 1932 revision by Royal Forest Department divided the forests in Thailand into 17 regions. An improvement in 1940 divided the forests in Thailand into 11 regions. A further improvement in 1952 was intended to establish 21 districts across the country, called "Forest Districts".
A Royal Decree, no.119, issue 99kor, dated 2 October 2002 stated: Under the Ministry of Natural Resources and Environment, Royal Forest Department remains responsible for economic forestry work and a new Department of National Parks, Wildlife and Plant Conservation is further established, which is divided into 16 regions with 5 branches for the conservation, promotion and restoration of natural resources, wildlife and plant species in forest areas.^[1]

• PARO 15 (Chiang Rai) with eight national parks.

• PARO 16 (Mae Sariang branch) with five national parks.

The Protected Areas Regional Office 11 (Phitsanulok) is a Thai government unit under the Department of National Parks, Wildlife and Plant Conservation, one of the Protected Areas Regional Offices of Thailand. Since the beginning one hundred years ago, forest management of office 11 (Phitsanulok) has undergone many changes, in form of reclassifications, name changes and management changes.

In 1901, an agency called "Forest Region Phitsanulok" was established under the Royal Forest Department, Ministry of Interior, responsible for the following 7 provinces: Kamphaeng Phet, Phetchabun, Phichit, Phitsanulok, Sukhothai, Tak and Uttaradit. Royal Forest Department was reclassified from the Ministry of Interior to the Ministry of Kasettrathikarn in 1921.
"Office Forest Region Phitsanulok" was built near Chan Palace in 1924. A 1932 revision by Royal Forest Department divided the forests in Thailand into 17 regions, "Forest Region Phitsanulok" has 5 provinces to administer: Phetchabun, Phichit, Phitsanulok, Sukhothai and Uttaradit.
An improvement in 1940 divided the forests in Thailand into 11 regions, "Forest Region Phitsanulok" was responsible for 7 provinces: Kamphaeng Phet, Phetchabun, Phichit, Phitsanulok, Sukhothai, Tak and Uttaradit.
Further improvement in 1941 renamed "Forest Region Phitsanulok" to "Forest District Phitsanulok", responsible for 4 provinces: Phetchabun, Phichit, Phitsanulok and Uttaradit. A further improvement in 1952 was intended to establish 21 districts across the country, called "Forest Districts", "Forest District Phitsanulok" was still responsible for the 4 original provinces in 1952. In 1975, "Forest District Phitsanulok" was renamed "Forest District Office Phitsanulok".^[1]

A Royal Decree, no.119, issue 99kor, dated 2 October 2002 stated: Under the Ministry of Natural Resources and Environment, Royal Forest Department remains responsible for economic forestry work and a new Department of National Parks, Wildlife and Plant Conservation is further established, which is divided into 16 regions with 5 branches for the conservation, promotion and restoration of natural resources, wildlife and plant species in forest areas. The name changed to "Protected Areas Regional Office 11 (Phitsanulok), PARO 11.
DNP regulation no.1241/2547 dated 27 July 2004, determined that management office 11 is responsible for 4 provinces: Nan, Phetchabun, Phitsanulok and Uttaradit. DNP regulation no.1808/2547 dated 15 November 2004, restricted the main areas to 3 provinces: Phetchabun, Phitsanulok and Uttaradit.
Its management is divided into 3 entities: National Parks and Forest Parks, Wildlife Sanctuaries and Non-hunting Areas, Botanical Garden and Arboreta.^[1]

Since the Fine Arts Department has renovated the Chan Palace as a historical monument, PARO 11 (Phitsanulok) has to find a new place. On 23 June 2013, the foundation stone was laid for the new building in Tha Thong subdistrict, Mueang district, Phitsanulok province. Later on 25 January 2015 the Chan Palace area was abandoned and handed over to the Fine Arts Department. In Somdet Phra Naresuan the Great Army Camp, 4th Infantry Division, was the temporary office. The new, a typical Thai government building was inaugurated on 2 October 2017.^[1]
